Hi. I have just bought this application but i already am almost giving up to enjoy this application. can you please tell me how to solve this problem?
As soon as I click "Update DB" in order to apply 3rd party airports, fsipanel says "Error Copying Makerws.exe, update will now stop". what can i do to apply those airports?

Hi,
...just an idea but are you starting FSiPanel with administrator rights?
If not, and you have installed FSX/P3D to C:\Programs, then you will certainly get this error as FSI is unable to copy makerwys.exe to the FltSim rootdirectory.
As I say.. just an idea!
Kind regards
Simon

Hi. Thanks for replying. Sadly, I’ve tried to do it again as an administrator right (and it was set as an default already) , and tried to touch “update dB”, nothing changes... (p3d are located in E:/LocheedMarten/...)

did you receive my Private message on the forum?
I sent you the email for the support.

I suspect that you have the Windows 10 protected folders options ON and FSiPanel can't copy MakeRwys.exe to C:\program files...
You need to give FSiPanel an exception in the Windows setup and then it should work.
